Amount schema `value` type is expected to be a number and not a string

[bbenligiray]

This is how amounts are represented

{
  "unit": "ether",
  "value": 1
}

Since value may still be a big number, it should be represented as a string and not a number type.
For reference, ethers.utils.parseUnits(1, 'ether') throws and ethers.utils.parseUnits('1', 'ether') succeeds.

I thought of that possibility when implementing this, hence the following check:

airnode/packages/airnode-validator/src/config/config.ts

Line 79 in 0b7d89e

value: z.number().lte(9007199254740991), // 2**53 - 1

But why not make it a string instead? For example, I think it's very likely for someone to want to do this

{
  "value": "1000000000000000000",
  "unit": "wei"
}

It actually used to be a string (under various earlier variable names e.g. priorityFeeSchema), but no one had a strong preference, see here for the discussion in which you comment: #890 (comment)

Let's leave the issue open anyway in case it comes up again
